As regards the question you asked in your letter about a concealed
group of masters in the Himalayas or anywhere else, there is no
foundation whatsoever for this in the Bahá’í Writings. We as
Bahá’ís must not believe in the divine origin of any such things
which have not been mentioned in our own Sacred Scriptures by
either the Báb, Bahá’u’lláh or the Master.

There is nothing whatsoever to lead us to believe that there is
any foundation or truth in these mystical stories of beings that are
“behind the scenes” so to speak. We must avoid such thoughts and
teachings, and try to wean others away from them as we give them
the Message….

He hopes that, now that a Board has been appointed by you and
your fellow-Hands in Europe, the teaching work in the goal
countries as well as in France and England will go forward much
more rapidly; and also that the pioneers opening up the many
new territories and islands in the Mediterranean and in the North
Sea areas will likewise benefit greatly from the assistance this
Board can give them ever increasingly.
